Both IEC 61850 [1] and IEC 61970 [2] define the access mechanism to the substation electric utility's data and data architecture. But they use a different approach in the access mechanism. IEC 61850 is defined from the internal communication standpoint whereas IEC 61970 is from the substation management standpoint. Thus, harmonization [3] is required to integrate both sides. In this paper, we'll discuss about harmonization methodology and its derivative problems and finally about the direction research should take.

With respect to characteristics of block trading rules, integrating various implementation mechanisms of demand side bidding (DSB), block bidding mechanism is extended to demand side and theory framework of block bidding mechanism incorporating demand side participation is proposed. Based on electricity pool pattern and with block bidding rules, electricity sellers and buyers can perform electricity trading in bilateral block bidding electricity markets. Furthermore, this paper analyzes implementation scheme of bilateral block bidding in detail, including block classification method, bidding rules and market clearing algorithm etc. The framework is beneficial to effective demand side participation in electricity markets, strengthens the relation between electricity supply and demand, and enhances energy trades efficiency.

In recent years, introduction of alternative energy sources such as solar energy is expected. The solar heat energy utilization systems are rapidly gaining acceptance as some of the best solutions for the alternative energy sources. However, thermal energy collection of solar heat energy utilization system is influenced by solar radiation and weather conditions. In order to control the solar heat energy utilization system as accurate as possible, it requires method of solar radiation estimation. This paper proposes the thermal energy collection of solar heat energy utilization system based on solar radiation forecasting at one-day-ahead 24-hours thermal energy collection by using three different NN models. The proposed technique for application of NN is trained by weather data based on tree-based model, and tested according to forecast day. Since the tree-based-model classifies the meteorological data exactly, NN will train the solar radiation with smoothly. The validity of the proposed method is confirmed by computer simulations by use of actual meteorological data.

Load forecasting plays a vitally important role in the operation and planning of the power system in a deregulated electricity market. A large variety of methods have been proposed for load forecasting. In this paper, we introduce the Graphics Processing Units (GPU) based computing to accelerate the short term load forecasting with Multi-layer Perceptron (MLP). The proposed method is tested with the Queensland electricity market demand series. The result shows that the GPU based computing largely reduce the computational cost.

When electric faults take place in onsite power system of nuclear power plants, the voltage of safety related bus can be affected such as voltage sag or dip. The safety related buses in nuclear power plants have a role of supplying vital power to essential loads for instrumentation and control of plant and safety shutdown of reactor. The risk of nuclear power plants will be increased if the voltage sag of safety related bus is occurred. Therefore, it is important to analyze the effect on voltage quality of safety related bus due to electric faults in nuclear power plants. This study performs that the characteristics of safety related bus voltage by different fault locations, types of faults, and plant status is simulated and analyzed.

This paper presents the voltage operation guidelines for the 345kV substations of Korea Power System. We used SVR(Secondary Voltage Regulation) theory for the development of Guidelines. For the division of control areas CESI[1] algorithm was used and EMS snapshot PSS/E datas were used for the study. The best target voltages for the pilot(reference) buses were calculated by Optimal Power Flow. By analyzing EMS snapshot datas we could find the control area voltage band and some other operation strategies.

This study presents the Angular Particle Swarm Optimization(APSO) algorism which is an optimization technique, in order to reconfigure micro-grids. Micro-grids are concepts of distribution system that unifies directly with customers and distributed generations(DGs). It could supply the electric power to customers and do the power transaction using a power market by operating the economic dispatch through several DGs of diverse cost function. If there are a large number of micro-grids in one distribution system, it needs to adjust the configuration of many micro-grids in order to supply the electric power with the minimum generation cost to all customers who are under the distribution system. So this study offers the APSO algorism which applies to the optimization technique, the algorism has multidimensional vectors that consist of magnitudes and phase angles.

In many countries, the electric power system and market interconnection is undergoing. Especially in Europe, there is a large interconnection project aiming pan-European power market. ETSO and Europex charged to develop harmonization of network access rules propose flow-based market coupling to manage cross-border congestion. In this methods, Power transmission distribution factor (PTDF) is used to measure sensitivity of the bids to the congestion. It is a simple way of understanding how much generation effect on congested line, but it depends on choosing slack bus. This paper describes slack independent sensitivity algorithm for a flow-based capacity allocation method.
